GPX file of PWNT route used to generate the 5km and 25km trail buffers (corridors)
SentiStrength was used as the sentiment analysis tool (Thelwall et al., 2010) SentiStrength Homepage
Viewshed analyses were conducted for each overall positive and overall negative tweet: - Viewshed Area - Land Cover - Ruggedness (St. dev. of elevation) - Extent of ESS agreements
Link to interactive web map of PWNT user sentiment
Conclusion - Sample too small to assess the effectiveness of ESS from the trail user perspective.
| Viewshed Analysis | Positive Tweets (mean) | Negative Tweets (mean) |
|---|---|---|
| Visibility from tweet location | 2.19 | 1.73 |
| Majority land cover class | 4 | 4 |
| Majority land cover % | 42.13 | 36.37 |
| Ruggedness Index | 1.47 | 1.70 |
| % of ESS agreements | 65.22 | 55.66 |
